[Intel-gfx] [PATCH] drm/i915/guc: Protect against HAS_GUC_* returning true values other than one

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

At the moment HAS_GUC_UCODE == HAS_GUC == IS_GEN9 ==
(INTEL_INFO(dev)->gen_mask & BIT(8)), which is true but not one. And
module parameters are integers and not booleans so compiler will not
normalize the value for us.

Quick and easy fix for the GuC loading code and the whole area can
be evaluated afterwards.
